INTRODUCTION Objectives and Procedures Sunflower performance tests were conducted in 29 by the Kansas Agricultural Experiment Station provide farmers, extension workers, and private industry with unbiased agronomic information on many of the sunflower hybrids marketed in the state. s were financed in part by entry fees from private companies. Companies known be developing and marketing sunflowers were invited participate and enter hybrids on a voluntary, fee-entry basis. As a result, not all hybrids grown in the state were included in tests, and hybrids were not grown uniformly at all locations. locations in 29 were Thomas County-irrigated and fallow; Greely County-irrigated; Ellis County-dryland; and Labette and Hutchinson Counties-dryland. seed entries were grown at all locations. Confectionary entries were evaluated in Thomas County-irrigated and fallow; Greeley County-irrigated; and Hutchinson and Labette Counties-dryland. seed and confectionary entries were planted separately in all tests. Entries were planted in four-row, replicated plots at all locations. To ensure uniform and adequate stands, all tests except those in Thomas County were planted at a high seeding rate and were hand thinned after emergence desired stands. s in Thomas County were planted stand with a modified Monosem Vacuum er. Environmental facrs affecting test results and cultural practices are presented for each individual test site. results for 29 and period-of-years average data are included in Tables 1 through 11. Entrants and entries in 29 tests are listed in Table 12. Data Interpretation s are reported as pounds of seed per acre adjusted 1% moisture content. Days half bloom is the number of days from date of planting the date when 5% of plants are in bloom. percentage is based on counts of lodged and tal plants in harvested areas at all locations. percentage was obtained from samples submitted under code number the Kansas Grain Inspection Service for analysis and is reported on a 1% moisture basis. Samples for all tests were derived by compositing replications by entry for each location and subsampling. yields are reported as net pounds of oil per acre. -size percentage analysis for confectionary-type entries was performed at the Northwest Research- Extension Center on cleaned samples submitted from each of the tests. Separation by seed size was made by screening a weighed sample through a series of six sieves (22/64, 21/64, 2/64, 19/64, 18/64, and 16/64-round holes) secured on a Ro-Tap mechanical shaker. Statistical analysis: Conducting perfect tests is virtually impossible because soil fertility, moisture, and other environmental facrs vary. Therefore, small differences in results might have no real meaning. To help interpret data, we applied a statistical technique, analysis of variance, whenever possible. Such analysis requires repeating whole sets of varieties or treatments several times and placing individual varieties or treatments as they would be placed by chance alone. Results of the analyses are reported in terms of least significant differences (LSD). If two means differ by more than the LSD (.5), such a difference would be due chance variation only 5% of the time. So, it's 95% probable that the difference was due treatment. If means do not differ by as much as the LSD, little confidence can be placed in the importance of varietal or treatment differences. The coefficient of variability (CV) represents an estimate of the precision of replicated yield trials. Trials with a CV ranging from 1% 15% are usually acceptable for performance comparisons. Trials with a CV greater than 15% provide only a rough guide hybrid performance. ACKNOWLEDGEMENTS Cooperation of research center personnel who performed many of the field operations is sincerely appreciated. Vicki Brown, secretary, and Jane Lingenfelser, Kansas Crop Performance s coordinar, assisted in preparing this report, and temporary worker Jenny Dickman helped with seed counting, plot thinning, and maintenance. Mary Knapp at the Weather Data Library provided climalogical data. - 1 -
